BEIJING - The arrival in China of President Obama's daughters, 15-year-old Malia and 12-year-old Sasha, for a weeklong trip with their mother, prompts the question: What about President Xi Jinping's daughter? Xi's daughter, Xi Mingze, never appears in public. The 21-year-old is believed to be a student at Harvard University, enrolled under a pseudonym. That has never been mentioned in the Chinese press and searches of her name on the Chinese Internet are blocked. The most recent photo of her available was from when she was about 10. The only other confirmed photograph, released last year by Chinese state media, shows her riding on the back of her father's bicycle when she was about 5. In contrast, the Obama girls have been splashed all over the Chinese media, deplaning in shiny taffeta skirts on Thursday.

When President Obama says he has the best healthcare in the world, he isn't kidding. The White House medical unit, with a staff of four doctors plus nurses and physicians' assistants, is steps from his office. Treatment is free for Obama and his family (as well as for the vice president and his family). During the president's travels, a doctor and nurse ride in a limousine in his motorcade. An emergency medical technician comes too, with an ambulance.

Christmas morning began early for the Obama family, which is vacationing in a rental home in Kailua, on the east side of the Hawaiian island of Oahu. The White House said the Obamas exchanged Christmas gifts at 8 a.m. They ate breakfast and sang Christmas carols before leaving for church at a nearby Marine Corps base. Obama wore a navy polo shirt and khakis, while the first lady wore a white dress with an orange band around the waist, according to the media pool report.

HBO has acquired a still-untitled documentary about President-elect Barack Obama that will air on the premium cable channel next year. The film, produced by Edward Norton and his production company Class 5 Films, was shot over the last 2 1/2 years with the cooperation of Obama and his campaign. Documentary filmmakers Amy Rice and Alicia Sams, who served as co-directors of the project, had access to Obama's staff, family and friends. Filming is continuing through the inauguration. -- Matea Gold

In 1960, after John F. Kennedy decided to move his convention acceptance speech from the brand-new Sports Arena to the larger Los Angeles Memorial Coliseum next door, he addressed a crowd of 80,000 from a stage that seen through 21st century eyes looks innocent and modest, if not clumsy. On the front of the lectern, just beneath the microphones, was a simple sign, its capital letters as skinny as Kennedy's tie, reading "Democratic National Convention." Below that, a large painted eagle spread its wings.

The spirits of two great men, Abraham Lincoln and Martin Luther King, Jr., stood watch over the West Front of the United States Capitol on Monday as Barack Obama took the oath to serve a second term as president with his left hand placed on two Bibles -- one Lincoln's and one King's. The event not only fell on the King holiday and 50 years after King's “I Have a Dream” speech, but also came within days of the 150thanniversary of Lincoln's Emancipation Proclamation. Without the revolutionary changes for which Lincoln and King were martyred, Barack Obama's presidency would not be possible.

First Lady Michelle Obama said Wednesday that her recent trip to a D.C.-area Target store was hardly a rare occurrence -- and that sometimes she sneaks out of the White House with a canine companion. "I do that more frequently than people realize," Obama told NBC's Al Roker on the "Today" show. "It's amazing how people don't recognize you. They don't expect to see me at Starbucks or at Chipotle. ... I actually took Bo to Petco. " Bo, of course, is the Obama family dog. "The cashier asked me, 'Oh, what kind of dog is that?

A painting depicting President Obama was defaced at an art gallery in the Sacramento area last weekend, and the gallery owner has vowed to keep the painting on display. The act of vandalism, which was reported by news station Fox40, occurred last week at The Brickhouse Gallery near the Oak Park section of the city. The painting of Obama, which sits on the roof of the building, was spray-painted with the words "No War" and the initials NWO, which apparently stand for New World Order, a conspiracy theory.
